Klizan definitely needs more bounce with the court to enact his game. Rui's game is pretty adaptable to most surfaces. He's a clay courter but has shown HC ability in the past. He took a set and was competitive with Federer in Davis Cup earlier this year.

Klizan said : "There is a big hall, which provides many actions, not only sport. Surface is really catastrophic, very soft and there are some parts, where ball do not bounce at all.
Everyone is complaining about that, but we cannot do anything. By the organisation side, there are not normal rest place for players, no gym. My expectations were pretty high, cause it is the first year of the tournament, which is told to be the best challenger tournament with biggest prize money.
By the way, it is not fair that Belluci plays this tournie due to players, that have been playing challenger tour for almost whole year, while Thomaz is ranked about 35 and plays only and only ATP World Tour. Then it is not kind of Challenger Masters."

So if Sela will win in straigt sets he'll qualify as num.2 (the other result is not matter in this case)If sela will win in 3 sets and Stebe will loose Sela would qualify s num.2 If sela will win in 3 sets ans Stebe will win in 3 sets Sela would qualify as num.2 If sela will win in 3 sets ans Stebe will win in straigt sets (I'm not sure but) the game number will decide (there's a option that the match between sela and Stebe and then Sela qualify)
Sela and Stebe will loose in straigh sets Bachinger will qualify i think
